The decision framework
PEBA
Population Exposure Burden Avoided
One score that ranks any intervention — a freight reroute, a school buffer, a fleet policy — by how much human exposure burden it removes. Cities and enterprises use PEBA the way lenders use a credit score: to decide.

What can you do with PEBA?
Five decisions the score was built to make.
Budget prioritization
Defend every rupee with avoided burden
Rank clean-air and adaptation spending by health return. PEBA turns a budget line into a defensible statement: this allocation avoids this much exposure burden, for these people.
₹ per exposure-hour avoided
Health burden reduction
Target the burden, not the average
Find the wards, corridors, and hours where exposure concentrates on the vulnerable — and act there first. Equal AQI does not mean equal harm.
−18.4k exposure-hrs/day · top action
Smart city intervention planning
A ranked queue, not a wish list
Freight rerouting, school buffers, transit priority, greening — every candidate intervention scored on one comparable scale before capital is committed.
144 wards · one decision queue
Scope 3 decision support
Choose actions boards can stand behind
Score commute, fleet, and logistics interventions by emissions and human impact together — and report the difference in BRSR / CSRD-compatible terms.
emissions × exposure, one score
Public health impact
Evidence that survives review
Attribute burden to geography and source with documented methods — the evidence base for targeted programs, advisories, and grant applications.

Four dimensions, one score
01
Exposure
Pollutant concentration experienced by people — not at the monitor, but where they actually are, hour by hour.
02
Population
How many people occupy the exposed space and time — residents, commuters, workers, students.
03
Vulnerability
Who they are: age, health status, occupation, and socioeconomic capacity to avoid or recover from exposure.
04
Time
Duration and timing of exposure — a peak-hour corridor and a quiet night street are different problems.
Methodology, openly documented
PEBA is built to survive procurement diligence and peer review. Every score traces back to named data sources and documented models:
- Exposure surfaces from fused satellite, ground monitor, and mobility data
- Population presence modeled from census, mobility, and land-use signals
- Vulnerability indices from demographic and health-capacity indicators
- Burden estimation aligned with WHO exposure-response functions
- Intervention scoring: counterfactual burden with vs. without action
